Standpoint is to let Ethiopia keep the money, or get the money and then turn it over into food for Ethiopian kids or something, but legally, Nestle has every right to it.

It's not lke their doing something heinously illegal or wrong. They just aren't particularly polite.

I'd add that I'm sure Nestle isn't being arbitrary about this. This is a real dilemma for them; they're caught between a rock (shareholders/bottom line) and a hard place (public opinion/reputation). And there may indeed be something valid in their claim that for foreign investment to work in such countries, there need to be assurances that principles of international law will be upheld.

That said, the best thing to do would be to have Nestle turn the money back over and make sure it's used to address real needs.
